MIT may have just made a major breakthrough in battery technology

38 sec read

Batteries simply haven’t been able to progress at the same rate that the technologies depending on them have, though this isn’t due to lack of trying. Researchers for organizations both public and private have been trying to find a breakthrough in battery technology for years, but none have really succeeded… until now. 

One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle — sometimes doubling in volume, and then shrinking back. This can lead to repeated shedding and reformation of its “skin” layer that consumes lithium irreversibly, degrading the battery’s performance over time. Now a team of researchers at MIT and Tsinghua University in China has found a novel way around that problem: creating an electrode made of nanoparticles with a solid shell, and a “yolk” inside that can change size again and again without affecting the shell. The innovation could drastically improve cycle life, the team says, and provide a dramatic boost in the battery’s capacity and power.
